I have a Lightning FLIR camera and it works identically well when used with Apple’s Lightning-to-USB-C adapter, it even works with my 2018 iPad Pro which kicked-off the iOS+USB-C process all those years ago. My iPhone today is rather aged (and uses Lightning) so I’m switching to an iPhone 16 later this year, and I’m confident all of my Lightning accessories will continue to work do long as the apps are available on iTunes. Related question: now that desktop iTunes is useless for iPhone app management - how the heck do I save and load the iOS I’ve purchased after they’ve been pulled from the store?
